Considering a move to bioplastics? Consider the experience of John Deere, which is now in the eighth year of a program to use soybean and corn feedstocks that was not originally driven for green reasons. The biomaterials are used in combine panels, backhoe loader hoods, and tractor hoods. Greg McCunnn, who runs the project, says the materials must be cost competitive and must be a performance drop-in for petroleum-based plastics. Needless to say, significant supply chain work was involved, and included funding from the United Soybean Board. Ashland Specialty Chemicals developed polyester resins that include soy and corn feedstocks, while processors Ashley Industrial Molding and Budd (currently Continental Structural Plastics) worked on the molding side. There were also issues related to painting and mold release.
And it amounts to more than a hill of beans: each combine made with the compound uses 1.1 bushels of soybeans and 0.5 bushels of corn.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
